TQ ALL IT MAY: CONCERN` Be it known that we, S'TVILLM'AN THORPE and WESLEY THORPE, both of Turner, in the eounty of Androsc'oggiu, and State ofiv Maine, have invented a new and useful Improved Car-Coupling; and we hereby declare thev following to be a full, clear, .and exact description thereof, which will enable others to make and use our invention, reference being had to the accompanying drawings, forming part of this specification, in which-f Figure 1,'plate1, is a view in perspective of our invention att-ached to cars. I l

Figure 2, plate 1, is a detached view ofthe weighted bolt. Y Figure 1, plate ,2, a sectional elevationV of the buffers shown in iig.` 1, plate 1.. Figure 2, plate 2, a perspective of the sliding backJ its slotted arm, and notch. Same letters show like parts. l .Y i Y Our invention has for its object the production of a quick and easy method for coupling ears, and consists of certain devices, by the arrangement andoperation -of which we seekto. secure this end. l

a and respectively,`shw two buiiers'attached to cars, as common. The mouth or'open part., of these bu'ers is made iiring at the top, bottom,` `and sides,'as"illustrated in 'theidrawing This we do not relaim. c shows tho tomamos. is honow.V oz-iso. sndirfg'or movable book, aoainoo aio hollow ortho honors. oo the -rear' face of this slide is albar o'r arm` attached. to said slide, ,said arm -moving in the hollow of the bar c, e

shows this arm. 4 vUpon. the"i`ront face of the slide d is 'a projection,f. Through the bottom ofi-'the buffersis insertedpthe weighted bolt g, working easilyin a hole -in said bottom, and having a lip orshould'er. a' shows the lip; z','the weight. j shows an'otchin 4the bottom of vthe slide d, in order to allow it to move over the head of the weighted boltpprojecting somewhat within the hollow of the buffer. '7c-shows the pin arranged to drop through the holeil, at the top of,v thebuier. Our invention employs but one link, which is represente-d atm.

By the use of thesedeviceswe obtain a shackle that couples thecars bythe impact offth'e two buffers, when the cars are brought together, or, V'in other` words, our invention is automatic or self-shackling in its operation. A

The operation is as follows: When two cars creto be shaekled together the end of the link that is within thehollow of the buffer is placed underneath the lip or shoulder z.,'on the head of'l the weighted bolt. This maintains the link in a horizontal-position, and prevents the said link, lwhen, the two cars come together, from it from striking Vthe sliding back d, and thus beingpushed within' the hollowof the, buffer, which would prevent coupling. This is'the arrangement which is made with. the bufferin which the link is placed. In the buier ofthe car to be unitedwith this, the following arrangement is made:-The sliding back d is ,drawn forward until -the projectionfpasses under the hole l, sothat the pin 7c may rest on 'said projection, as shown in iig, 1,' plates ,1 aud 2. `Asthe two cars now come together, the lin-k in its butter, sustained and held in position by the weighted bolt as beforeldescribed, will push backward the sliding 'back cZ in the other bniier, thus releasing the pin 'in saidbuficr, and allow it to drop through the holes in the butler, through the link, and thus unite the cars. VFor better security the pindrops into a hole'in the bottom of the butter. .The arm e has a slot, y, through which passes thepin zo, and throughthe bar c, in order vto allow thel sliding back-.cl to-inove backward and for` ward, and still retain, it in'thevhollow of the buffer.I4 If desired, a rngmay be attaehedto the front face of the sliding back, for eonveniencein drawing it forward, ora hollow may be Vmade on the under side of the projec'- tion f, as illustrated in the drawing. It will be understood that the bueriin .which the sliding baekfis pushed backwardlwhen the ears .come together, isthe one in which the link is not placed; but it makes no difference in which ofthe two buiers to` two approaching ears the link is placed, provided the other buier is arranged for the impact of the two, as before'described. i

We do not.claim an automatic car-shackle, neither do we claim releasing and dropping the pin by the impact of the cars; We are aw'are of Letters Patent gran-ted to Warren D. Hatch, No. 6,754, in 1849, andwe do not claim the combination of a spring tongue with'a self-acting guided coupling-pin, arranged as set forth. in` said patent. Neither. do weI desire to claim the employmentof a slide fitted into the draw-head in grooves, and

having c pendent plateiand spring arranged to operate as set forth in,the rejected application of H. Lefevre and A. Ellmaker, received and filed March 19, 1863.

`The construction and operation of our invention is different from `either of these, first, from the fact oi" the absence of any spring in the sliding back- .piece d, and its arm y, which spring is liable Mto get out of repair; Second, in the use of the weighted bolt g with its head h, for the purpose Aof sustaining tlieflink in a, position to enter the'opposing draw-head. The operation is dicrent, inasmuch as the vsliding back piece d, in the absence of a, spring, must he drawn forward by hand to support the pin k, as shown invone-haif of fig. 1, plate 2. The

'slot of the arm y and the pin a: fitting therein is also different. These dierences prevent our invention from being entirely :Ltom'atic in :L11 its operations, hutincrease its capacity for wear.

But what We do claim, anti desire t0 secure by Letters Patent, is- The combination and arrangement of the sliding backd, slotted arm y, and pm 9;, with the coupling-pin c, in connection with the Weighted bolt g and link m, as and fox` the purposes set forth.
